Abstract

<P>PROBLEM TO BE SOLVED: To achieve the remarkable improvement of boiler efficiency and the saving of fuel by using the boiler applying sodium nitrate as a primary medium. <P>SOLUTION: This boiler is constituted in such manner that the sodium nitrate as the primary medium starts its melting from 120°C, and moderately heated up to 600°C to be a thermal storage state, when it is heated as a stand-alone state. Here, the longer the heating time is, the larger the temperature difference between the primary medium kept into contact with a flame tube and that kept into contact with a second medium, becomes, and the thermal storage effect of the primary medium can be exercised. Further high efficiency and fuel saving can be achieved by using a material of high heat conductivity as a material of a can body to improve the effect in heat absorption/radiation of the primary medium and by applying a vertical/lateral structure. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明が属する技術分野】
本発明は、熱媒体を使用したボイラーに関するものである。
【0002】
【従来の技術】
熱媒体に水、またはオイルを1次加熱して、温水、蒸気また熱交換器等に使用しているのが従来であり、ボイラー効率を上げるためボイラー構造の改良、及び燃料の燃焼効率の改善が進められてきた。
【0003】
しかし、水またはオイル等はバーナー等の高温の熱源で加熱しても熱の吸収効率が良い媒体ではなく、加熱した熱量の約15%は利用されずに外部に放出されてきた。
【0004】
今地球の温暖化が進んできているのも、この様なエネルギー効率の悪さも原因の一つに上げられると思われる。
【0005】
この改善策として、熱吸収効率の高いボイラーが出来た。
【0006】
【発明が解決しようとする課題】
解決しようとする課題は熱効率の向上とボイラー効率の向上である。
【0007】
【課題を解決するための手段】
本発明は、熱吸収性にすぐれ又放熱性が良い特性を持つチリ硝石を1次媒体に使用することである。
【0008】
【発明の実施の形態】
チリ硝石を1次媒体に使用したことで、熱効率がよくボイラー効率の良いボイラーが実現した。
【0009】
【実施例】
図−1は、本発明装置の1実施例の断面図であって、熱源が炎管を通過するとき1次媒体が加熱され、 次に2次媒体が加熱される様子を図示したものである。
【0010】
【実施形態の効果】
チリ硝石は加熱すると温度上昇速度が速く、加熱を停止すると温度冷却速度が速いと言う特性が有り、
一方水は温度上昇速度が遅く、冷却速度が遅いと言う特性が有ります。この特性を利用すると、
図−1で示すように炎管を熱源が通過すると、1次媒体のチリ硝石は熱を吸収しやすい特徴を発揮して、
高効率で吸熱し2次媒体に放熱する。
【0011】
しかし2次媒体は熱吸収が遅く1次媒体からの放熱を全て受け止められません。そこで1次媒体は吸収 されなかった熱を蓄熱し徐々に温度が上昇して来る。
【0012】
加熱を停止した時、蓄熱された1次媒体からの放熱により2次媒体の温度が上昇する。
【0013】
この様に1次媒体の蓄熱効果を発揮させるのに、1次媒体の量を増加し、1次媒体の熱源に接する面積を増加させ、1次媒体と2次媒体との接触面積を増加させる事により高効率のボイラーが出来た。
【0014】
【発明の効果】
この様にチリ硝石を1次媒体としたボイラーを使用する事によりボイラー効率の飛躍的な上昇による 燃料の節約に大きく貢献出来た。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a boiler using a heat medium.
[0002]
[Prior art]
Conventionally, water or oil is primarily heated as a heat medium and used for hot water, steam, heat exchangers, etc. The boiler structure has been improved to increase the boiler efficiency, and the fuel combustion efficiency has been improved. Has been advanced.
[0003]
However, water or oil is not a medium having good heat absorption efficiency even when heated by a high-temperature heat source such as a burner, and about 15% of the heated heat has been discharged to the outside without being used.
[0004]
It is thought that such poor energy efficiency is one of the causes of the global warming that is progressing now.
[0005]
As a remedy, a boiler with high heat absorption efficiency was created.
[0006]
[Problems to be solved by the invention]
The problem to be solved is to improve thermal efficiency and boiler efficiency.
[0007]
[Means for Solving the Problems]
An object of the present invention is to use chile saltpeter having excellent heat absorbing properties and good heat radiation properties as a primary medium.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
By using Chile saltpeter as the primary medium, a boiler with high thermal efficiency and high boiler efficiency was realized.
[0009]
【Example】
FIG. 1 is a cross-sectional view of one embodiment of the apparatus of the present invention, showing how a primary medium is heated when a heat source passes through a flame tube, and then a secondary medium is heated. .
[0010]
Effects of the embodiment
Chile saltpeter has the property that the temperature rise rate is fast when heated, and the temperature cooling rate is fast when heating is stopped,
On the other hand, water has the characteristic that the temperature rise rate is slow and the cooling rate is slow. Using this property,
As shown in Figure 1, when the heat source passes through the flame tube, the primary medium, Chile saltpeter, exhibits the characteristic of easily absorbing heat,
It absorbs heat with high efficiency and radiates heat to the secondary medium.
[0011]
However, the secondary medium has a low heat absorption and cannot receive all the heat radiation from the primary medium. Therefore, the primary medium stores the heat that has not been absorbed and the temperature gradually rises.
[0012]
When the heating is stopped, the temperature of the secondary medium rises due to heat radiation from the stored primary medium.
[0013]
In order to exert the heat storage effect of the primary medium in this manner, the amount of the primary medium is increased, the area in contact with the heat source of the primary medium is increased, and the contact area between the primary medium and the secondary medium is increased. The result was a highly efficient boiler.
[0014]
【The invention's effect】
In this way, the use of a boiler using Chile saltpeter as the primary medium has made a significant contribution to fuel savings due to a dramatic increase in boiler efficiency.
[Brief description of the drawings]
FIG. 1 shows a positional relationship among a primary medium, a secondary medium, and a flame tube as a vertical section of a boiler.
